| Description | HNMT Human Recombinant fused to 36 amino acid His Tag at N-terminal produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 328 amino acids (1-292) and having a molecular mass of 37 kDa. The HNMT is purified by proprietary chromatographic techniques. |
| Protein Background | HNMT is located in the cytosol and uses S-adenosyl-L-methionine as the methyl donor. In the mammals brain,N(tau)-methylation controls the neurotransmitter activity of histamine since diamine oxidase is not located in the central nervous system. A well known genetic polymorphism influences the activity levels of HNMT gene product in red blood cells. HNMT inactivates histamine by n-methylation. HNMT is involved in degrading histamine and in regulating the airway response to histamine. Histamine is involved in regulation and modulation of immune response through the stimulation of four distinct subtypes of receptors, H1, H2, H3, and H4, that present on the target cells. Histamine is inactivated by the histamine-metabolizing enzyme HNMT in bronchus, kidney, and the central nervous system. |
| Expression host | Escherichia Coli. |
